Stereochemistry , a subdiscipline of chemistry , involves the study of the relative spatial arrangement of atoms that form the structure of molecules and their manipulation. For this reason, it is also known as 3D chemistry—the prefix "stereo-" means "three-dimensionality". An important branch of stereochemistry is the study of chiral molecules.

Written in English. Stereochemistry of Organic Compounds The first fully referenced, comprehensive book on this subject in more than thirty years, Stereochemistry of Organic Compounds contains up-to-date coverage and insightful exposition of all important new concepts, developments, and tools in the rapidly advancing field of stereochemistry, including. Chapter 1 describes first the stereochemistry of the ground state, specifically the configuration and conformation of organic compounds, as well as the most important.

Let's first discuss a few basic concepts. Although most people are accustomed to thinking of organic chemistry as a bunch of drawings and structures, this "paper chemistry" is not really how these molecules act in real life. Of course, these molecules are really three-dimensional shapes, and not just 2d drawings. Stereochemistry aims to explain the natural phenomena of spatial arrangements of these organic molecules. Stereocenter : Any atom in a molecule that is attached to 4 different atoms.

Stereochemistry of Organic Compounds: Principles and Applications. Nasipuri 1 January by D. The new book is almost three times as large, reflecting the rapid growth in this field. Stereochemistry of Organic Compounds Ernest L.

Ball, John W. Hill, and Rhonda J. Scott is for the one-semester General, Organic and Biological Chemistry course.

This book provides an overview of fundamental concepts of asymmetric synthesis highlighting the significance of stereochemical and stereodynamic reaction control. In-depth discussions of asymmetric synthesis with chiral organolithium compounds, atropisomeric biaryl synthesis, self-regeneration of stereogenicity SRS , chiral amplification with chiral relays and other commonly used strategies are also provided. Particular emphasis is given to selective introduction, interconversion and translocation of central, axial, planar, and helical chirality. A systematic coverage of stereochemical principles and stereodynamic properties of chiral compounds guides the reader through the book and establishes a conceptual linkage to asymmetric synthesis, molecular devices that resemble the structure and stereomutations of propellers, bevel gears, switches and motors, and topologically chiral assemblies such as catenanes and rotaxanes. Racemization and diastereomerization reactions of numerous chiral compounds are discussed as well as the principles, scope and compatibility of commonly used analytical techniques.

Chemistry of Waste Minimization pp Cite as. The history of optical isomerism goes back to the year , when the phenomenon was discovered by the French physicist Jean-Baptist Biot [1]. Optical activity was defined as the ability of a substance to rotate the plane of polarisation of light. Some years later, his student, Louis Pasteur [2] proposed that this optical activity of certain organic compounds was a consequence of their molecular asymmetry, that produces non-super-imposable mirror-image structures. A molecule which is not superimposable on its mirror image is said to be chiral.

Танкадо - мастер высокого класса, он никогда не оставил бы висячие строки, тем более в таком количестве. Эти висячие строки, или сироты, обозначают лишние строки программы, никак не связанные с ее функцией. Они ничего не питают, ни к чему не относятся, никуда не ведут и обычно удаляются в процессе окончательной проверки и антивирусной обработки. Джабба взял в руки распечатку. Фонтейн молча стоял. Сьюзан заглянула в распечатку через плечо Джаббы. - Выходит, нас атакует всего лишь первый набросок червя Танкадо.

 - Уже обо всем пронюхали. Сьюзан отвернулась от экрана ВР к боковому монитору. На нем бесконечно повторялась видеозапись убийства Танкадо.

Сьюзан было запротестовала, но Стратмор не дал ей говорить. - Вы меня не знаете, молодой человек. Я рисковал всю свою жизнь. Хотите меня испытать. Что ж, попробуйте! - Он начал нажимать кнопки мобильника.

Такое впечатление, что он его буквально всучил - канадцу показалось, будто бы он просил, чтобы кольцо взяли.

Поднявшись по мраморным ступенькам, Дэвид подошел к двери, и она точно по волшебству открылась. Привратник проводил его в фойе. - Багаж, сеньор.

 Там подают отличный карпаччо.  - Хейл улыбнулся.  - Что скажешь. А потом мы могли бы… - Выкинь это из головы. - Сколько в тебе снобизма.

С какой стати вы решили послать туда моего будущего мужа. - Мне был нужен человек, никак не связанный с государственной службой.
